iriver (formerly iRiver) is a consumer electronics company headquartered in South Korea and widely known for its digital audio players and other portable media devices.
The company is a brand and marketing division of Iriver.inc (formerly ReignCom), a South Korean electronics and entertainment company founded in 1999 by seven former Samsung executives.
iriver's current products can all play MP3 and WMA audio files. Some units support text viewing, Ogg Vorbis audio files, Macromedia Flash, and/or BMP files. The company also supports Microsoft PlaysForSure, which allows recent products to support subscription-based music download services, including URGE, Napster, Rhapsody, and Yahoo! Music Unlimited. It also lets users disable its DRM functionality.
A nearly unique feature of the newer iriver players is the direct MP3-recording capability with selectable bitrate of internal (FM, microphone) and external (line) sources.
Many players support multilingual display in English, French, Spanish, German, Italian, Chinese, Japanese and Korean. They support Winamp playlists and allow repeat, shuffle play and programmable functions. Several preset and one user-defined EQ settings are included, plus a built-in FM tuner.
Most iriver players include a unique feature called study mode. Users can quickly jump back and forth within tracks by a certain time interval, set from three to 180 seconds in current models. The option was designed to help people listening to recorded language lessons. SonicBlue removed this feature from its Rio Volt models, causing some users to hack their players with iriver firmware from other regions.
